## Computing basics

---

## File/directory awareness
+ Every computer has a file/directory system
+ There's a default or home folder
   
   ```r
   ## use this to see your home folder
   normalizePath("~")
   #> [1] "/Users/kearneymw"
   ```
+ Files are organized like a tree
   - You can move from one branch to another
   - Moving from one folder to another is linear

---

## Bash shortcuts
+ Most popular conventions from bash/terminal found in R scripts
   - **`..`** to go back a folder or **`../..`** to go back two folders
   ``` sh
   ls ../tidyverse
   ls ../..
   ```
   - **`~`** as a shortcut for home, e.g., **`~/R/stat`**
   ``` sh
   ls ~/R/stat
   ```

## Don't fall asleep yet!
Why should you care?

+ Because you need to know where things are to interact with them!
+ Because you want to be able to replicate your work!

> **tl;dr**: Open your file browser.
> **tl;dr**: See how they're organized?
> **tl;dr**: Yeah? Good!

---

## Don't let these terms confuse you

+ **File** is **name**/location of a file
+ **Folder** is **name**/location of a file folder

+ **Path** is name/**location** of a file
+ **Directory** is name/**location** of a file folder

## FutuRe you
Using scripts and writing clear code makes life easier

+ It's writing down point/click routines you don't have to memorize
+ Internet is full of scripts you can customize
+ With some notes and attention, future you will be very happy with current you!
